How Software Works From First Principles: From Electrons and Silicon to the Programs You Use
By
faza
Summary
A deep, first-principles exploration of how software actually works, starting from the physical reality of electrons flowing through purified silicon circuits. The article traces the entire stack from transistors and logic gates to arithmetic, memory, programming languages, and the software abstractions we use daily. It demystifies the "absurdity" of modern computing by building up understanding from the most fundamental physical layer to high-level software.

· 3 pulledWhen you use your smartphone or laptop, it is easy to forget the sheer absurdity of the physical reality underneath.
Behind that seamless experience lies centuries of effort from physicists, chemists, mathematicians, engineers, programmers, and designers.
By just controlling the flow of electrons inside these circuits, we are able to make the rock calculate, remember, and think for us, sparing us the mental effort.
